Retro 80s Triathlon? What do you think?

Someone jokingly posted something about how there should be a retro triathlon in the forum on another thread a while back and it's been stuck in my head ever since.  I've been thinking and researching what kind of rules there would be for a race like this.  Here's what I've come up with, what would you add/change about them?

1. Your bike must be from the 80s or older.
2. No fancy new wheelsets, no bladed spokes etc   -Any bike that is questioned for it's retro validity would be put to a participant vote.
3. No carbon fiber is allowed
4. No TT helmets (but new bike helmets would be required for the safety aspect)
5. No Gu, Hammer Gels, Cliff Bars, Shotblocks, or any other new-fangled electrolite/recovery stuff.  -Your choices would be water or Lemon-Lime or Orange Gatorade (since those were the original two flavors)
6. No dry-fit shirts or other synthetic fabrics like under-armor and stuff.

A couple things that could depend on whether it's an "early 80s" or a "mid-late 80s" Retro Tri would be:

Clipless pedals have been around for a while (since the 1800s) but didn't become a commercial success until around 1983 since they were considered death traps. Hinault used them in Le Tour in '86 and Lemond and Hinault used them in '87.   So an 'early 80s' could ban clipless pedals and require flat pedals or clips.

The first triathlon specific wetsuit was made in the lat 80s, like 1988 or 1989 I believe.  So do you hold it in a warm enough month that you can ban wet suits or do you only allow surfing wetsuits?

Aerobars were first used in 1986 for the RAAM and then popularized by Lemon in 1989 at Le Tour.  So an "early 80s" tri could ban then, but a "mid-late 80s" would allow them (but remember... no carbon)

based on my 10 year old bike shorts and their complete lack of a chamois like they have now I'd think that padded bike shorts are banned... but neon colored spandex shorts are highly encouraged.

Should everyone have to wear some vintage style Adidas or Nike running shoes?
